That's pretty odd. I'd have put money on you putting the acpi=off line
on the kernel command line rather than Xen's, but it looks like you have
it right.

Have you checked to see whether there's a BIOS update that fixes the
acpi issues? Turning acpi off should only be used as a last resort.

Also, have you tried booting from the demo CD and having a poke around.
Does it see your hardware OK?
